JOURNAL-BEARING.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed December 26, 1907. Serial No. 408,178.

To all whom it may concern:

Hyde Park, in the county of Norfolk and State of Massachusetts, haveinvented certain new and useful Improvements in Jourrial-Bearings; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to journal bearings, and the object of thepresent invention is to provide an adjustable journal bearing whichshall be of simple and cheap construction, and which shall be firm andsolid in all positions within the range of adjustment.

With these objects in view, the present'intop plan of the journalhousing and the adjusting. wedges; and Fig. 4 is a vertical section online 4-4, Fig. 3.

As shown in the drawings, the housing 1 for the bearing comprises a baseand sides rising vertically therefrom. Fitted within this housing andloosely enough to provide for proper adjustment is the pillow block 2,in which is formed or carried the lower half of the bearing proper. Thepillow block is provided with substantially vertical ends 3, sides 4,and flat bottom 5. The four bottom corners are beveled, as it were,giving inclined plane surfaces 6. A smaller beveled surface 7 connectseach side 4 with the bottom 5. The beveled corners of the pillow blockare engaged by two pairs of wedges 8 having inclined surfaces, and thetwo wedges of each pair are moved toward and from each other by means ofa right and.

; ing the sides of the rabbets and holding the Be it known that I,GEORGE W, ALLEN, citizen of the United States, residing at 15 on theupper ends of the studs 14 secure the can to the housing and hold thepillow block and adjusting wedges securely within the housing. Shims 16may be inserted between the cap and the pillow block, one or more ofwhich may be removed from time to time to take up wear in the bearing.

The bearing is adjusted by actuating the threaded spindles 9. Forinstance, if the nuts 15 be slightly loosened and the lefthand spindle10, shown in Figs. 1 and 8, be turned clock wise, the wedges 8 will bedrawn toward each other, forcing the pillow block and cap to the rightand upward. If the right-hand spindle be turned in the same direction atthe same time, the pillow block and cap will be forced in a verticaldirection, while if one spindle be turned in one direction and the otherspindle in the other direction and to the same extent, the block and capwill be moved horizontally in one direction or the other. The bearingmay be thus adjusted in any direction and to any extent within thelimits.

Not only is the present form of bearing simple in its arrangement andexceedingly cheap in construction, owing to the fact that very littlemachining isnecessary, and owing to the self adjustability of the parts,which avoids the necessity of extreme accuracy in their shape anddimensions, but the pillow block being supported upon plane surfaces isfirmly held at all times, no matter what its adjustment may be.

Having set forth the nature and object of the invention, andspecifically described one form of apparatus in which it may beembodied, what is claimed is 1. A journal bearing comprising a housing,a pillow block fitting loosely within the housing, and having four planesurfaces an gularly disposed each to the other, wedges cooperating withsaid surfaces on the pillow block, and means for moving the wedges toadjust the pillow block, substantially as described.

2. A journal bearing comprising a housing having a base, a pillow blockfitting loosely within the housing and adapted to be adjustedtransversely of the axis of said bearing in both a vertical and ahorizontal direction, and having a plurality of plane surfaces inclinedto each other and to both the vertical and horizontal transverse axes ofsaid bearing, and wedges between the pillow block and the base of thehousing to adjust the pillow block in the. housing, substantially asdescribed.

3. A journal bearing comprising a housing having a base and sides atright angles to said base, a pillow block fitting loosely withinthe-housing and adapted to be adjusted toward and from said base andtoward'and from said sides, and having a plurality of plane surfacesinclined to each other and to both the base and the sides of thehousing, movable wedges engaging the base and sides of the housing andcooperating with said inclined surfaces for adjusting the pillow block,a cap, and means for clamping the cap to the housing to hold the pillowblock in adjusted position in the housing, substantially as described.

4. A journal bearing comprising a housing, a pillow block fittingloosely within the housing and having its four bottom corners beveled,wedges for engaging the beveled corners, and means for moving the wedgesto adjust the pillow block, substantially as described.

5. A journal bearing comprising a rectangular housing, a pillow blockfitting loosely within the housing and having its bottom cornersbeveled, wedges for engaging the beveled corners of the pillow block,means for moving each of a pair of wedges simultaneously toward or fromeach other, a cap held in fixed position relative to the pillow block,and means for securing the cap to the housing having provision forvertical and transverse adjustment'of the cap, substantially asdescribed.

6. A journal bearing comprising a housing, a pillow block fittingloosely within the housing and provided with a plurality of inclinedplane surfaces, a plurality of wedges movable in the same plane inparallel paths and having inclined plane faces intersecting the plane ofmovement of the wedges in lines oblique to the path of movement of saidwedges, substantially as described.

7 A journal bearing comprising a pillow block provided with a pluralityof plane faces inclined to each other and to the vertical and horizontaltransverse axes of the bearing, a plurality of wedges having inclinedplane surfaces for supporting the pillow block and movable to adjust thepillow block transversely of the axis both vertically and horizontally,a support for the wedges, and means having provision for adjustment ofthe pillow block both horizontally and vertically transverse of the axisof the bearing for clamping the pillow block upon the wedges in adjustedposition, substantially as 1 described.

8. A journal bearing comprising a housing, a pillow blockfitting looselywithin the housing, having its four bottom corners beveled, and having ashoulder at its top,

engagement with the shoulder on the pillow block to prevent relativemovement of the pillow block and cap'transverse to the axis of thebearing, and means having provision for vertical and transverseadjustment of the cap and block for securing the cap to the housing andfor holding the cap and block in the adjusted position, substantially asdescribed.

9. A journal bearing comprising a housing, a pillow block adjustablewithin the housing and having four plane surfaces an-.

gula-rly disposed each to the other and to the axis of the bearing,movable wedges cooperating with said plane surfaces to adjust the pillowblock, and means for securing the pillow block in adjusted position,substantially as described.

10. A journal bearing comprising a pillow block having diagonallyopposite bottom corners beveled, wedges for engaging the bev- 5 eled'corners to support the pillow block, means for movin the wedgesto adjustthe pillow block, an devices for securing the pillow block in adjustedposition, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses.
